SPIKED SHOE.

To all whom it may concern Be it known that I, JAMES S. CALDWELL, a citizen of the United States, residing at KansasCity, in the county of Jackson and State of Missouri, have invented certain new and useful Improvements in Spiked Shoes, of which the following is a specification.

This invention relates to spiked shoes for baseball players and the like, and my object is to produce shoe plates which will enable the wearer to maintain his footing while running in a straight, curved or tortuous course, or in assuming an attitude or position where he is off balance or braced to start suddenly in any direction, and which furthermore will eliminate to a large degree, the chance of injury to a player accidentally struck by the spikes, as very frequently occurs in the game of baseball where a player slides feet first in an attempt to gain or steal a base.

lVith this general object in View, the invention consists in certain novel and peculiar features of construction and organization as hereinafter described and claimed, and in order that it may be fully understood reference is to be had to the accompanying drawing, in which Figure 1, is an inverted plan view. of a shoe equipped wit-h plates embodying my invention. Fig. 2, is a side view of the plates and part of the shoe. Fig. 3, is a cross section on the line III-III of Fig. 1.

In the said drawing, 1 indicates a shoe, and secured to the sole thereof by securing devices or rivets 2, is a T-shaped plate 3, arranged with its head extending transversely, and its stem projecting forwardly.

Depending from the end of the head adja cent the inner edge of the sole, is a pair of inwardly-converging dull or rounded spikes 4c and 5, and from the opposite end of the head depends a pair of similar inwardlyconverging calks or spikes 6 and 7. Preferably spikes 4 and 7 and 5 and 6, extend 1n parallel planes respectively.

Depending from the front end or extremity of the stem of the plate and extending convergingly rearward is a pair of dull or rounded spikes 8 and 9, spike 8 preferably extending at an angle paralleling that at which the spikes 5 and 6 extend, and spike 9 at an angle paralleling that at which spikes 4 and 7 extend, and depending also from the stem is a dull or rounded spike 10, the same being preferably of slightly greater Specification of Letters Patent.

height than the other spikes, for a purpose which hereinafter appears.

The plate described may be of any suitable material and may be cast or stamped from sheet metal, in which latter case the various spikes described will be hollow and yet possess the requisite strength and rigidity.

A plate of substantially the same type and numbered 11, is secured to the heel of the shoe, though it is to be understood in this connection, that the arrangement and relation of the spikes on the heel plate is unimportant as any spikes depending from the heel, which will give a firm grip upon the ground may be used, it being desirable, however, that the spikes of the heel plate shall be dull or rounded to minimize chance of injury to any one with whom they may come in more or less forcible contact.

When the wearer is standing at rest, most of his weight is imposed on the spikes of the heel plate and spikes 4t and 6 of the sole plate which latter spikes will be slightly embedded in the ground. In the event he makes ready to start forward and hence leans slightly in that direction, his weight is removed from the heel plate and is imposed mainly on spikes 4 to 7 inclusive, and spike l0, and as he starts to run, the center of gravity is shifted further forward and the spikes 8 to 10 inclusive, constitute the supports and resistance points. In the event the wearer makes ready to start sidewise, or

' is standing in such position that his bracing foot is disposed crosswise of the direction in which he expects to run, the weight is largely imposed on the spikes 4 and 5, or if he leans forward, on the spikes 5, 8 and 10. In reaching overhead with both hands, as in catching an overhead fly ball, one foot is usually thrown forward as a brace, and in this case the spikes 4t and 5 of the advanced foot will constitute the chief points of resistance to slippage. 7

It will 'be'seen that any movement which will remove the weight from the heel will byreason of the increased height of the spike 10, efiect the embedment of the same in the groundat the same time that spikes 5 and 7 are embedded, and that the length of said spike 10 also permits it to cooperate with spikes 5 and 8 at times and spikes 8 and 9 at times.

If the spike 10 was of the same length as spikes 5 to 8, it would not be embedded in my h M an the ground with said spikes and 8, for instance, when the foot was occupying a position in which to apply a rearward and lateral thrust to enable the wearer to make a quick start.

In practically every position which the plate occupies when the wearer is in motion, or is poised for a quick start in any direc tion, one or more of the embedded spikes extends at an angle to the direction in which the movement will occur.

From the above description it will be apparent that I have produced a spiked shoe embodying the features of advantage enumerated as desirable and I wish itto be understood that while I have illustrated and described the preferred embodiment of the same, I reserve the right to make all changes properly falling within the principle of the invention as defined by the appended claims.

I claim:

1.- An anti-slipping device, comprising a plate adapted to be secured to a sole and provided with a pair of rearwardly-coa verging calks for location near the hall portion of the sole near the side margins thereof, and with a longitudinally extending calk in advance of said pair of calks to be positioned midway between the sides of the sole.

2. In an anti-slipping device, a plate adapted to be secured to a sole and carrying a pair of rearwardly converging calks for location at the ball line of the sole, a pair of forwardly diverging calks for location near the toe of the sole, and a calk between said pairs of calks to be positioned midway between the sides of the sole.

In an anti-slipping device, a sole hav ing a plate attached thereto, said plate being provided with a pair of forwardly diverging calks spaced slightly from the toe end of the sole and with a calk at the rear of said pair of calks positioned midway between the sides of the sole.

4. An anti-slipping device, comprising a "i'shaped plate adapted to be secured to a sole with its head extending transversely and its stein projecting forwardly, a pair of inwardly converging depending spikes at each end of the head of said plate, a pair of rearwardly-converging depending spikes at the front end of the stem, and a longitudi- 1 na-lly extending spike depending from the stem.

5. In an anti-slipping device, a plate adapted to be secured to a sole and having a pair of rearwardly diverging calks adapted to be located beneath the ball portion of the sole near the margins thereof, a

pair of forwardly diverging calks for the toe of the sole, and a calk between said pairs of calks to be positioned midway between the sides of the sole and of greater height than the other calks.

6. An antislipping device comprising a plate adapted to be secured to a sole and provided with a pair of forwardly diverging calks for location near the toe end of the sole, a pair of outwardly diverging calks for location beneath the ball portion of the sole near one side thereof, and a calk intermediate said pairs of calks to be positioned midway between the sides of the sole.

7. In an anti-slipping device, a plate adapted to be secured to a sole and pro vided with a pair of outwardly diverging calks for location beneath the ball portion of the sole near the side thereof, and with a longitudinally extending calk in advance of said pair of calks to be positioned midway between the sides of the sole.

8. An anti-slipping device comprising a plate adapted to be secured to a sole and provided with a pair of rearwardly-diverging calks for location near the ball portion of the sole near the side margins thereof, and with a longitudinally extending call: in advance of said pair of calks to be positioned midway between the sides of the sole.

9. In an anti-slipping device, a sole having a set of three calks secured thereto, one of said calks being disposed longitudinally of the sole midway between the sides thereof, and the other calks being juxtaposed near the margin of the sole on the sameside of the longitudinal axis thereof and extending in an outwardly diverging relation toward the adjacent sole edge.

In testimony whereof I my signature, in the presence of two witnesses.
